DEVICE FOR APPLYING INSECTICIDES.

SPECIFICATION forming part of Letters Patent No. 507,615, datedOctober31, 1893.

Application filed Aprill5, 1893. Serial No- 470,523- (No model.)

To all whom it may concern:

Be it known that I, MARY A. HAWLEY, a citizen of the United States,residing at Dixon, in the county of Lee and State of Illinois, haveinvented certain new and useful Improvements in Devices for ApplyingInsecticides; and I do declare the following to be a full, clear, andexact description of the invention, such as will'enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention has reference to improvements in devices for applyingvermin destroying powder to fowls, and consists of means by which thefowls, in passing in and out of the hen-house, sprinkle such powder uponthemselves.

The-present application comprises improvements upon the construction forwhich I obtained United States Letters Patent No. 472,456, on April 5,1892, by which the mechanism involved is simplified, and made moreeffective and durable.

I accomplish the above purposes by the construction shown in theaccompanying drawings, in which- Figure 1 is a perspective of myinvention. Fig. 2 is a detail of the concussive lever and some of itsadjacent parts.

Similar letters refer to similar parts in each View.

AA are'standards, seated a certain distance apart on the base S, anddrawn partially toward each other at their upper ends, one of saidstandards having the vertical portion B, and the other of said standardsthe vertical portion 0 and the diagonally outward projected end D.Between the vertical portions B and O, aforesaid, of the standards A,there is suitably seated, vertically, the insect powder containingvessel E, having its bottom provided with perforations F, suitablydistributed over such bottom.

G is a treadle board, either wooden or metallic, pivoted laterally at Hto the base S between the standards A, and adapted to oscillate on suchpivotal points in the line of the opening between said standards.

R is a double bell-crank lever, pivoted atJ 0n the upper extremity ofthe part D of one of said standards A. Said lever consists of one longhorizontal arm K, extended over the upper end of can E, and provided atits extremity with the concussing head L, the downwardly projecting arInM, provided at its extremity with the head N, hanging in its normalposition about parallel with the adjacent side of the can E, andprovided with the short arm 0, substantially in prolongation of the armK. v

P is a wire, or cord, attached at its lower end to the corner of thetreadle G, and extended vertically, and attached at its upper end to theextremity of the arm 0 of lever B.

The operation of my invention is as follows:The' device is placeddirectly within the opening of the hen-house, in such relation to saidopening as that the fowls, in passing in and out of the latter, arecompelled to step upon and walk over thetreadle G. The arms K and M areof such weight as to hold the side of the treadle G, to which the wire Pis attached, normally elevated a suitable distance above the earth, orfloor, of the hen-house. The passage of the fowls over the treadle G hasthe effect of forcing such wire attached end downward, and thereby,through the medium of said wire, depress the arm 0 of the lever B, andcause the end N of the arm M to strike the part 0 of the standard A, andas said part 0 is in contact with the can E, the concussion of such blowjars said can and causes a portion of the powder contained therein to besprinkled upon the fowl or fowls beneathsaid can being suspended, asaforesaid, about centrally above the treadle G. The action lastdescribed has the effect of raising the arm K above said can,and as theI fowl steps from, and thereby releases the treadle G, the arms M and Kconjointly incidentally raise said treadle, which causes the arm K tostrike the top of the part B of one of the standards A, and therebyimpart asec- 0nd concussion to said can, which will discharge anotherportion of said powder upon the fowl beneath, before the latter haspassed beyond the reach of said falling particles. If preferred, theheadsL and N may be arranged to strike the side and top of the can E,respectively; but, to prevent possible damage to said can, I prefer toreceive the blow on the standards A, as shown.

The advantage of my present invention is that each Whole movement of thetreadle G results in imparting two concussions to the can E, producingtwo successive discharges from thelatter, and thereby not only increasesthe quantity of discharge, but distributes the same over differentportions of the body of the fowl beneath.

The parts may be made of wood, or metal, or partly of each, as may bedeemed most desirable; but, in either event, should be Well coated, orpainted, for the purposes of preservation.

That I claim as my invention, and desire to secure by Letters Patent ofthe United States, is

1. The combination of the vertical standard A, the powder containing canE supported in the upper end thereof, the lever R pivoted at J to upperend of standard A provided with concussive arms K and M diverging fromsaid pivotal point, and an actuating arm 0, the treadle G pivotallyseated at the lower portion of said standard, and the rod, or wire,Pconnecting said treadle with said operating arm 0; substantially asshown, and for the purpose described.

2. The combination of a suitable vertical frame and treadle, seated inthe lower portion thereof, and an insect powder containing can seated inthe upper end thereof, the lever B fulcrumed in the upper end of saidframe, and provided with the concussive arms K and M adapted, in theoscillations of said lever, to. alternately jar said can, and with theactuating arm 0, and means, substantially as shown, for connecting saidlast named arm and said treadle, whereby the vertical oscillations ofthe latter are communicated to said lever for the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.

MARY A. HAWLEY.
